The woman appears to have stopped after another employee who was in the nursery leaves the room.

To make matters worse, Ms Oxendine said she was forced to rush her son - who was born prematurely and is lactose intolerant - to hospital on Friday evening after he fell ill and started vomiting.

"To me, a criminal act was committed against him... Not only did you put your breast to my son, you also made my son sick because he's lactose intolerant. So you've put something in his body that his body can't digest," Ms Oxendine said.

Ms Oxendine says the woman was fired following the incident but that wasn't penalty enough and she should face criminal charges.

Carrboro Early School day care director Daron Council said the woman who allegedly breastfed Ms Oxendine's son was licensed and had worked in childcare for over a decade.

Carrboro police confirmed they are investigating the matter as misdemeanour child abuse and no charges have been filed yet.
